1.2 PIN DESCRIPTION
VDD and VSS. Power is supplied to the MCU using
these two pins. VDD is power and VSS is the
ground connection.
open-drain (5V drive) in output mode while PC4 to
PC7 are open-drain with 12V drive and the input
pull-up options does not exist on these four pins.
OSCin, OSCout. These pins are internally con-
nected to the on-chip oscillator circuit. A quartz
crystal or a ceramic resonator can be connected
between these two pins in order to allow the cor-
rect operation of the MCU with various stability/
cost trade-offs. The OSCin pin is the input pin, the
OSCout pin is the output pin.
RESET. The active low RESET pin is used to start
the microcontroller to the beginning of its program.
Additionally the quartz crystal oscillator will be dis-
abled when the RESET pin is low to reduce power
consumption during reset phase.
TEST. The TEST pin must be held at VSS for nor-
mal operation.
PC0, PC1 and PC3 lines when in output mode are
“ANDed” with the SPI control signals and are all
open-drain. PC0 is connected to the SPI clock sig-
nal (SCL), PC1 with the SPI data signal (SDA)
while PC3 is connected with SPI enable signal
(SEN, used in S-BUS protocol). Pin PC4 and PC6
can also be inputs to software programmable edge
sensitive latches which can generate interrupts;
PC4 can be connected to Power Interrupt while
PC6 can be connected to the IRIN/NMI interrupt
line.
DA0-DA5. These pins are the six PWM D/A out-
puts of the 6-bit on-chip D/A converters. These
lines have open-drain outputs with 12V drive. The
output repetition rate is 31.25KHz (with 8MHz
